' Application filed May 25,1902, Serial No. 109,024.

.Yorlr, in the county of New Yorlrand State of No York, have invented-acertain new and useful Improvement in Mixing-Machines,

of which the following is 'a specification.

My invention relates to machines adapted for mixing concrete, mortar,and the like, and involving a rotary mixing-receptacle arranged upon amovable frame or support which can be operated for the purpose of tilt-'ing the rotary mixing-receptacle.

Ob ects ot my invention are to advantageously support the rotary mimn-receotacle and permit it to be readil T ti ted to ll 7 provide simpleand eliicient meansfor con tinuously rotating the mixing-receptacle toprovide simple and el'licient means for operating the frame or supportwhich serves to up. hold and tilt the rotary mixing-receptacle;

to apply power from an engine or motor for tilting the rotarymixing-receptacle from its recein'ng or mixing position to a positionfor discharge and also for-tilting the mixing-receptacle from itsdischarging position back to its receiving or mixing position; toautomatically disconnect such power at each end of the predeterminedextent of such tiltingmovement and also to permit an attendant toreadily disconnect the power for tilting at any point between said twoextremes or limit IV of tilting movement whereby the tilt of themixing-receptacle can be arrested at will; also, to simplii theoperating mechanism shown and described in my application for LettersPatent of the United States filed April 15, 1902, and serially numbered102,960.

in the accompanying drawings, Figure 1- is a side elevation of amixing-machine embodying the principles of my invention, the, mix.ing-receptacle being in position for receiving a charge of materials.Fig. 2 is a like view showing the mixing-receptacle tilted into 0-sition for discharging a mixed-up batch. I ig 3 is atop plan view-withthe miXing-receptacle removed. Fig. is an enlarged detail view, partlyin section and partly in'elevation, the section being on line :0 as inFig. 3. Fig. 5 is a section on line so rt in Fig. e. Fig. 6 is a sectionon line y 1 in Fig. 3. Fig. 7 is a section on line 2 z in Fi 3; Fig. 8is a vertical trans-- verse section oi the mixing-machine. 9

also engage anti receptacle revolves. V B is therefore arranged tooscillate about an is a detail View of the clutch-lever, and Fig.

and 2, respectively arranged at diagonally opposite corners thereof andrespectively providing the receptacle with charging and dischargepassages or openings. These hollow journals-0i the mixing-receptacle areupheld by antifriction-rolls 3 on the movable su port B.

' he movablesu pport B has a curved or segmental ortion provided with asegmental rack, Whic is engaged and operated by a driving-pinion, apreferred arrangement being to construct the movable support as a framehaving its segmental portion formed by curved side bars 4, each having acurved raclcbar 5. W ith such I arrangement the rack-bars are engagedbypinions 6 on a transverse shaft 7, and in order to further guide themovable iction-rol ls 8 on a standard 9, which rises from the bed-frame10. This movable support or frame B can be sustained by a bed havin anydesired number of antii'riction bed-rel s positioned at suitableintervals along the arc of a circle and will have ,a

rotary reciprocative movement when opersupfport its se mental bars 4 canated to tilt the axis about which the mixing- The sup orting frame axistransverse to the axis of rotation of'the mixingreceptacle, and as amatter of course when-it is thus operated its end portions which supportthe mixing-receptacle will tilt or tip, thereby varying the surge of thelongitudinal axis about which "the mixing-receptacle revolves.

The rotar' counter-shaft G is shown con: y

nected with the rotary hurting-receptacle by an endlesspower-transmitting belt or chain 4 i), and to such end the mixng-receptacle and thecounter-shait are respectively rovided withsprockets l i 12 such chain I the tilt of the counter-shaft.

g earns? or belt. The end portion of the countershaft, which is providedwith the chainor belt sprocket 12, is supported by a sleeve or bearing13, having a pivotal connection with the movable supporting frame B, asillustrated in Figs. 2, 4, and 5, in which the bearing-sleeve 13 has acouple of oppositelyarranged pivots or trunnions 14, supported to turnin a bracket formed by cheek-plates 15, bolted to a cross-bar 16 on themovable supporting-fran1e, Figs. 3 and 5.

'The counter-shaft C is operated by a driving-gear E and also has asliding connection therewith, and to such end the gear E has an axialbore in which the counter-shaft is fitted to slide. The gear E and thecounter-shaft C are connected by a spline 17, Fig. 4, on one of suchmembers engaging in a groove in the other member, whereby rotation ofthe gear will drive the counter-shaft and at the same time the latterwill be permitted to slide longitudinally in the gear. The gear E isalso pivotally supported by trunnions, so as to permit it to rock ortilt in conformity with As shown in Figs. 3 and 4, the hub portion 18 ofthe gear E is secured in a bearing 19, which is support ed; upon thebed-frame by trunnions 20 and 21, Fig. 4. With this arrangement thetron-- nion 21 is conveniently formed by one end of a transverse shaftF, having a bevel-gear H, whichengages and operates the beveled E. Whenshaft F is operated, the countershaft 0 will be driven therefrom and themixing-receptacle will be rotated byreason of its gear connection withsuch counter-shaft, and when the oscillatory frame B is moved. for thepurpose of tilting the axis of rotation of the mixing-receptacle theshaft C will slide one Way or the other through the rotating ear E, andthe latter will. rock or tilt in con-- i ormity with the tilting motionof the rotating and longitudiirally-moving counter-sh aft. Thislongitudinal shift on the part oi the countershaft E is illustrated bycomparing Figs. 2 and 8. In Fig. 2 the rotary mixingreceptacle istilted. for the purpose of discharging the mixed-up batch, and in 8 themixing-receptacle is in. position for receiving and mixing. It will beseen, however, that in both positions the axis of the countenshaft isparallel with the axis about which the mixing-receptacle revolves.

As a means for operating the oscillatory supporting-frame B the rotaryshaft 7, having pinions 6, which engage the racks on such frame, is alsoprovided with a worm-wheel G, which is engaged by a worm 22, Fig. 7, onthe rotary worm-shaft H, Fig. 7. The shaft H is mounted upon thebed-frame and is also provided at one end with a bevel-gear 23,

Fig. 3. The shaft H is operated from the main driving-shaft F bysuitable clutch mechanism, such as clutch hub or sleeve 24, Fig. 3,feathered to slide along and rotate with position illustrated in Fig. 2to the recei shaft F and having a couple of bevehgears 25, which. can.be alternately placed iii engagement with gear 23 for the purpose ofnmving the support B in opposite directions. in this connection Iindicates a clutch-lever piv- 7o oted upon the bed-frame and arrangedfor shifting the clutch device on shaft F. 'i lever i can also beautomatically ope ed for the purpose of arresting the moveu t oftheoscillatory support B at either of the two 5 extreme positions or thelatter. To such cud the shifting clutch member I has an arm 26, and thetilting frame upon which the min receptacle is mounted is provided w'tappets or stops 2? 2'7, spaced with rcrerence So to their requiredterms of service, one being" provided for engaging arm 26 of the lei asto shift the latter, and thereby "r ically disconnect the power fromwhen the mixing-receptacle been tilted to an extent to place it in apredetermincd position for uisrha ge, the other one of said stops orprojections 27 being provided to engage said lever-arm and. shift thelever so as to antomatically disconnect the power ironi shaft H when theini "-receptacle ample, been tilted back from the a...
